GdkEventScroll

Generated from button presses for the buttons 4 to 7. Wheel mice are usually configured to generate button press events for buttons 4 and 5 when the wheel is turned.

Some GDK backends can also generate “smooth” scroll events, which can be recognized by the GDK_SCROLL_SMOOTH scroll direction. For these, the scroll deltas can be obtained with Event.getScrollDeltas.

struct GdkEventScroll {

ModifierType state;

GdkScrollDirection direction;

}

Variables

deltaX double deltaX;: the x coordinate of the scroll delta
deltaY double deltaY;: the y coordinate of the scroll delta
device GdkDevice* device;: the master device that the event originated from. Use Event.getSourceDevice to get the slave device.
direction GdkScrollDirection direction;: the direction to scroll to (one of GDK_SCROLL_UP, GDK_SCROLL_DOWN, GDK_SCROLL_LEFT, GDK_SCROLL_RIGHT or GDK_SCROLL_SMOOTH).
sendEvent byte sendEvent;: TRUE if the event was sent explicitly.
state ModifierType state;: a bit-mask representing the state of the modifier keys (e.g. Control, Shift and Alt) and the pointer buttons. See GdkModifierType
time uint time;: the time of the event in milliseconds.
type GdkEventType type;: the type of the event (GDK_SCROLL).
window GdkWindow* window;: the window which received the event.
x double x;: the x coordinate of the pointer relative to the window.
xRoot double xRoot;: the x coordinate of the pointer relative to the root of the screen.
y double y;: the y coordinate of the pointer relative to the window.
yRoot double yRoot;: the y coordinate of the pointer relative to the root of the screen.
